General Description. Harriman Fiord is the northwestern arm of Port Wells, the northeastern branch being College Fiord. It has the form of a bent arm. The lower part of this fiord from Port Wells to the elbow is called Barry Arm. It extends northwestward from Pt. Pakenham for a distance of about 8 miles, Barry Glacier being at the elbow end (Map 8).
Harriman Fiord proper extends westward from the elbow of Pt. Doran at right angles to Barry Arm and then turns southwest, having a total length of over 12 miles, and terminating at the tidal front of Harriman Glacier. About half way down the western side is a tributary fiord 2$ miles long, terminated at the western end by Surprise Glacier. On the southern side of this inlet is Cataract Glacier, which descends the fiord wall to tidewater. About half way between Surprise and Barry Glaciers is the fifth tidal ice tongue of Harriman Fiord, Serpentine Glacier, which ends in a small cove. The other ice tongues of the fiord, none of which reach the sea, are Toboggan, Baker, Detached, Roaring, Dirty, Wedge, and a number of smaller ones. The snow line is at an elevation of 2000 to 2500 feet (PI. CXVH, B), and above it the proportions of snow covering and bare rock vary with the slopes.
Barry Arm and Harriman Fiord are from 1 to 3 miles wide and are bordered by steep fiord walls, rising from 8000 to 4000 feet within a mile of the fiord and with many peaks attaining greater heights, including Mt. Gilbert, 10,194 feet high, the highest peak in the western Chugach Mountains (PL CXXVII), at a distance of 5J miles from the fiord, Mt. Gannett,1 9240 feet high (PI. CXXVIH), 6 miles from the fiord, and Mt. Muir, 8207 feet, 2 miles from the fiord. Harriman Fiord lies in the very heart of the Chugach Mountains and the northern slopes of Mts. Gilbert, Muir, and Gannett supply ice for the TTnik Glacier which flows northward to the Matanuska Valley and the head of Cook Inlet. A high glacier between Mt. Gilbert and Mt. Gannett, visible from Port Wells, is probably a part of the north-flowing glacier system.
Previous Studies. The Barry Arm portion of Harriman Fiord was shown roughly upon maps by Vancouver in 1794,2 Applegate in 1887,8 and Glenn,* Castner B and Men-
